The second display body 121 further includes a second display surface121 b connected to the second side 121 a, and each positioningprotrusion 124 has an opening 124 b communicating with the cavity 124 a.To be specific, each opening 124 b is located on a movement path of thecorresponding engagement protrusion 125 a and faces away from the seconddisplay surface 121 b. Therefore, the engagement protrusion 125 a ofeach pendulum hook 125 may move out of the cavity 124 a or move back tothe cavity 124 a through the corresponding opening 124 b.

With reference to FIG. 2A and FIG. 2B, the first display surface 111 dis adjacent to the second display surface 121 b, and the two surfacesface the same direction in space. When each positioning protrusion 124is inserted into the corresponding positioning recess 111 b, eachopening 124 b is aligned with the corresponding engagement recess 111 c.Under the action of gravity, each pendulum hook 125 rotates (or swings)with respect to the positioning protrusion 124, so that each engagementprotrusion 125 a moves out of the cavity 124 a through the correspondingopening 124 b and is engaged with the corresponding engagement recess111 c.

Further, as a tilt angle of the second display 120 in space changes, aposition of the engagement protrusion 125 a of each pendulum hook 125changes. In states shown in FIG. 2A and FIG. 2B, the first displaysurface 111 d and the second display surface 121 b are parallel to adirection of gravity 101 or are tilted backward with respect to thedirection of gravity 101. Taking a notebook computer as an example, anunfolding angle of the first display 110 may be greater than or equal to90 degrees. Under the action of gravity, the engagement protrusion 125 aof each pendulum hook 125 moves out of the cavity 124 a through thecorresponding opening 124 b and is engaged with the correspondingengagement recess 111 c.

In this embodiment, each pendulum hook 125 further includes a pivotingportion 125 b pivotally connected to the positioning protrusion 124 anda counterweight portion 125 c connected to the engagement protrusion 125a, and the pivoting portion 125 b is away from the engagement protrusion125 a and the counterweight portion 125 c. That is, the center of massof each pendulum hook 125 falls on the counterweight portion 125 c andis close to the engagement protrusion 125 a. When the first displaysurface 111 d and the second display surface 121 b are parallel to thedirection of gravity 101 or are tilted backward with respect to thedirection of gravity 101, under the action of gravity, the counterweightportion 125 c of each pendulum hook 125 may drive the engagementprotrusion 125 a to move out of the cavity 124 a through thecorresponding opening 124 b.

As shown in FIG. 2B, each pendulum hook 125 further includes a positionlimiting portion 125 d, the position limiting portion 125 d is connectedto the counterweight portion 125 c, and the engagement protrusion 125 aand the counterweight portion 125 c are located between the pivotingportion 125 b and the position limiting portion 125 d. Further, eachpositioning protrusion 124 has a stopping portion 124 c adjacent to theopening 124 b, and the position limiting portion 125 d of each pendulumhook 125 is located in the corresponding cavity 124 a and abuts againstthe stopping portion 124 c. Therefore, the stopping portion 124 c ofeach positioning protrusion 124 may be configured to determine arotation (or swing) range of the corresponding pendulum hook 125, sothat most of the blocks of the pendulum hook 125 are accommodated in thecavity 124 a.

FIG. 4A is a schematic front view of the display apparatus of FIG. 2Abeing tilted forward. FIG. 4B is a schematic cross-sectional enlargementview taken along a cross-sectional line K-K of FIG. 4A. In FIG. 4A andFIG. 4B, the first display surface 111 d and the second display surface121 b are not parallel to the direction of gravity 101 and are tiltedforward with respect to the direction of gravity 101. Taking a notebookcomputer as an example, the unfolding angle of the first display 110 maybe less than or equal to 70 degrees. Under the action of gravity, theengagement protrusion 125 a of each pendulum hook 125 moves away fromthe corresponding engagement recess 111 c and moves back to the cavity124 a through the corresponding opening 124 b. At this time, theposition limiting portion 125 d of each pendulum hook 125 is separatedfrom the stopping portion 124 c.

After the structural interference between the engagement protrusion 125a of each pendulum hook 125 and the corresponding engagement recess 111c is lifted, the second display 120 may be detached from the firstdisplay 110 by the user, so that detaching and mounting may be easilyperformed.

In view of the foregoing, in the display apparatus provided by thedisclosure, as the positioning protrusion is matched with thepositioning recess and the second magnet is matched with the firstmagnet, the second display may be mounted at one side of the firstdisplay by the user, and the second display is also prevented from beingslidably detached from the first display. Further, after the positioningprotrusion is inserted into the positioning recess, and the second sideof the second display body contacts the first side of the first displaybody. When the pendulum hook is subjected to the action of gravity sothat engagement protrusion is engaged with the engagement recess,structural interference is generated between the engagement protrusionand the engagement recess, so that the second display is accordinglyprevented from being detached from the first display, and assemblyreliability of the display apparatus is enhanced. In contrast, when thependulum hook is subjected to the action of gravity so that theengagement protrusion moves out of the engagement recess, the structuralinterference between the engagement protrusion and the engagement recessis lifted, and that the second display may be detached from the firstdisplay by the user, and easy detaching and mounting is provided.
